Specification of Letters Patent.

To all whom it may concern: I

Be it known that I, JAMES S. WILSON, a citizen of the United States,residing at Chelsea, in the county of Suffolk and State ofMassachusetts, have invented certainnew and useful Improvements inApparatus for Vulcanizing Rubber Articles and the Like,

of which the following is aspecification.

This invention relates to certain new and useful improvements inapparatus for vulcanizing rubber articles and the like.

The object of the invention is to provide improved means for readilyvulcanizing rubber articles constructed in great lengths or sections.

' Application iiled m 21, lacs. Serial No. 508,850.

A further object is to provide an im proved vulcanizing apparatusconstructed of a plurality of separate sections capable of useindependently, or in stacks.

A further ob ect is to' provide a mold with means whereby the same maybe read-' ily changed or adapted to work of different A further objectis to provide improved means for feeding the green or unvulcanizedarticle to themold prior to the vulcanizing operation.

The invention will be hereinafter fully set forth and particularlypointed out in the claims. I Y v In the accompanying drawings :Figure lis a side elevation illustrating a plurality of molds assembled in astack for the vulcanizing process, parts being broken away and shown insection. Fig. 2 is a plan view of one of the mold sections illustratingthe article in position to be vulcanized. Fig.

3 is a transverse sectional View of one of the.

mold sections. Fig. 4 is a similar view of a slight modification. Fig. 5is a similar view of a second modification. Fig. 6 is an enlarged planview illustrating the feedingdevice. Fig. 7 is a side elevation thereof.Fig. 8 is a detail.

Referring to the drawings 10 designates a table or platform'secured to ashaft 11 and supported adjacent its periphery by suitable antifrictiondevices 12 mounted upon arms 13. The shaft llis provided with a beveledgear 14 driven by a. pinion 15 receiving power from any suitable source.The table, 10 is constructed to support a mold 16, or if desired aplurality of said molds may be built up one upon the other to form astack, asshown in Fig. 1.' Each mold consists of a body 17, preferablycirinterior heating chamber 18receiving steam,

or other heating medium from any suitable source. In each. face of themold is formed a continuous spiral channel 19 as clearly illustrated inFig. 2. In Fig.4 these channels are shown as cast integralinto the moldbody. In Fig. 3 said channels are shown as formed in plates 20 which areremovably secured to the bodyof the mold by means of screws 21 or otherpreferred securing devices; By employing these removable plates 20channels of-difierent form may be readily substituted one for the otherupon the same jacketed mold body to conform to the size and contour ofthe article to be vulcanized. In Fig. 5 the-mold is shown without theheating chamber, this form being adapted to be placed in an ordinaryvulcanizing device ofanf suitable or preferred construction. In order tobring the super- -posed mold sections in juxtaposition" when PatentedMay 20, 1913.

cular in contour, and provided with an 'placedone upon, the other, Iprovide each 'mold section with projecting lugs 23 arranged to entercomplemental recesses 24 in the contiguous edge of the next adjacentsection. Each section also provided with lugs carrying uide pins 25,which engage holes 26-forme in lugs 27, the lugs carrying the pins andholes .being arranged alternately. The pins of one section fit withinthe holes of the next adjacent section, thereby holding the sections inproper relative position. When the several mold sections have beenplaced one upon the other they are locked together by means of rods 28engaging lugs 29 carried by each section, pressure being applied bytightening the nuts 30 carried by said rods. In the drawings I haveillustrated the apparatus as in the act of vulcanizing rubber hose, butit is obvious that the invention is not of articles. As shown eachsection of hose carried by the various mold sections is coupled at 31with a fluid or other pressure device 32 by means of which an internallimited to this class 1 a homogeneous mass which becomes permanentlyinseparable.

,The green or unvulcanized article may be placed in the spiral channels19 in any suitable manner. I have illustrated, however, a feeding devicecomprising a reel 40 mounted in suitable arms 41 and adapted to receivethe unvulcanized-article. Said article, which as before stated isillustrated as a hose or tube, passes between upper and lower feed ingrolls 42, mounted in a suitable carriage 43, carried by a shaft 44arranged diametrically across the mold. Said carriage is provided with aguide wheel 45 adapted to fit within the channel 19, and extendingrearwardly from said carriageis a bracket 46 which supports a placingwheel. 47. The wheel 45 rests within the course of the channel 19 nextadjacent the course in which the wheel 47 isplacing the. hose. In orderto prevent the unvulcanized material from adhering to the feeding rolls42 and the placing wheel 47 the latter are made hollow to receive'talcwhich is'sprinkled over the material thrpugh suitable perforations 48 inthe peripheries.

In practice the unvulcanized article having been previously wound uponthe reel 40 in any suitable orpreferred manner, the

guide wheel 45 is placed within the channel 19 and the end of thearticle brought into position in the outer course of said channel. Asthe table 10 is rotated the traction of wheel 45 rotates the feed wheels42 thereby feeding the article from the reel 40 and permitting the wheel47 to place the same in the channel, the said reel being arranged toreciprocate back and forth to deliver the hose in line with the channel.When the desired length has been placed in position a second mold may beplaced over the first in the manner heretofore described, the channel 19on the underside of the latter registering with thecorresponding'channel in' the top face of the first section. After thedesired number have been superposed one u on the other the sections ofthe stack are loo ed together and the connections made with the fluidpressure. At the same time the heating medium is directed to theinterior of the molds. After the required time has elapsed the molds areseparated and the foregoing operation repeated, as desired. After thevulcanizing process, the vulcanized article is-removed from the mold,commencing with the end located in the outer course of the channel.After two or three of the courses of said channel have been emptied, thefeeding wheels 42 may be operated to place a new article in the moldsimultaneously with the removal of the remainder of the vulcanizedarticle. It is obvious that while I have shown and described the moldsections as arranged in a stack, the same may if desired be usedindividually without departing from the spirit of my invention. It isalso obvious that the stack may be made up of mold sections adapted todifferent styles, sizes and contours.

It will be noted that the channel faces of my improved mold sections areso constructed that in the event of injury toany of said faces, thechannels may be readily recut or dressed down by any of the well knownmachines or apparatus adapted to such work.-

I claim as my invention 1. A vulcanizing apparatus comprising two moldsections, each formedupon its face with a continuous coiled channel, thechannel of the two sections when the two sections are assembled, forminga continuous coiled chamber to hold the article to be vulcanized, asteam chamber or chambers formed in each of said sections, a feedingdevice comprising a reel and carriage, feeding. rolls mounted thereon, aguide wheel mounted in said carriage engaging one of said mold sections,an arm rojecting from said carriage, and a placmg roll mounted in saidarm.

2. In a vulcanizing apparatus, the combination with a vulcanizing moldprovided with a spiral channel of a feedin device comprising a reel, acarriage, feeding rolls mounted therein, and a guide wheel mounted insaid carriage and engaging said channel.

3. In a vulcanizing apparatus, the combination with a vulcanizing moldprovided with a spiral channel of a feeding comprising a reel, acarriage, feeding rolls mounted therein, a guide wheel mounted in saidcarriage and engaging one course of said channel, and a placing rollmounted in said carriage and located adjacent a contiguous course insaid channel.

4. In a vulcanizing apparatus, the combination with a vul'camzing mold,of a feeding device comprising a reel, a carriage, feeding rolls mountedthereixhand a guide wheel mounted in said carriage and engaging saidmold, said feeding rolls being hollow to receive talc or the like andprovided with perforated peripheries whereby the unvulcanized materialis prevented from adhering to said rolls.

In testimony whereof I hereto afiix my signature in presence of twowitnesses.
